Abstract

feasibility study on the issues related with introducing a Coordinated Cadastral System (CCS) for Malaysia. One of the several project themes that has been carried out is a study related to the legal traceability issues concerning GPS for cadastre, testing of GPS equipment, and recommended practices for GPS cadastral surveys in the country. The practice of cadastral surveying which is regulated by legislation requires distance measurements (by EDM or chain) that are traceable to primary standards of measurement by means of calibration. However, the implications for GPS cadastral surveying are unclear as GPS position is not a defined physical quantity. An alternative solution to the problem of GPS legal traceability using the conventional approach of calibration against a standard being proposed. It has been identified that a set of recommended practices or guidelines regarding the use of GPS for Cadastral surveys in the country need to be developed. The guidelines concerning among others the survey planning and design, the testing/calibration of GPS equipment, the selection of the appropriate GPS field technique, and the related field and office operation procedures. Results on the GPS equipment testing and calibration
